| 摘 要： | 在分析双馈感应发电机（doubly-fed induction generator,DFIG）运行特性和传统最大风能追踪控制（maximum power point tracking，MPPT）策略的基础上，给出一种基于约束因子限幅控制的DFIG有功功率平滑控制策略，提出功率输出限幅值可调的控制思想，结合发电机转速控制和风力机变桨距控制来实现输出功率保持在任意给定值。给出了约束因子的表达式和取值规则。在Matlab／Simulink仿真平台上采用所提平滑控制策略，对一个9MW风电场的有功功率输出特性进行研究，计算了2种控制策略下输出功率的平滑性能指标和方差值。实验结果表明，与传统最大风能追踪控制策略相比，所提出的平滑控制策略能显著减小发电机输出功率的波动，优化了系统的电能质量。

| Abstract: | On the basic analysis of the operating characteristics of doubly-fed induction generator(DFIG) and conventional control strategy of maximum power point tracking(MPPT),a new control strategy based on constraint factor for extent-limit to smooth the active power output of DFIG was proposed.This method could provide a adjustable limit value of active power output,which combined the generator speed control and pitch angle control to keep the active power output at any given value.The expression and calculation ... |
